fetchmail is a utility that retrieves and forwards mail from
|
|
remote systems using IMAP, POP, and other protocols. It ships with
|
|
fetchmailconf, a graphical utility used to create configuration files.

<p>
|
|
Thomas Wolff discovered that fetchmailconf opens the configuration
|
|
file with default permissions, writes the configuration to it, and only
|
|
then restricts read permissions to the owner.

|
|
<p>
|
|
A local attacker could exploit the race condition to retrieve
|
|
sensitive information like IMAP/POP passwords.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Run "umask 077" to temporarily strengthen default permissions,
|
|
then run "fetchmailconf" from the same shell.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All fetchmail users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-mail/fetchmail-6.2.5.2-r1"</code>
